Description

Technical Field

[0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an anaerobic fermentation tank stirring device for sewage treatment. Background Art

[0002] At present, sewage treatment in the livestock breeding, oil drilling, refining, chemical, electric power, pharmaceutical, and medical industries has attracted increasing attention, and the requirements for sewage discharge standards are becoming increasingly higher. Conventional sewage treatment technology is usually pretreatment → biological treatment → deep treatment. In this process, the anaerobic tank is an important link in the sewage treatment system, usually located before the biochemical tank, and plays a role in pretreatment and preliminary decomposition of organic matter.

[0003] Anaerobic biological treatment technology is an efficient sewage treatment method in which the organic matter in sewage is decomposed, metabolized, and digested by anaerobic bacteria under anaerobic conditions, which greatly reduces the organic matter content in sewage and produces biogas. Among them, anaerobic fermentation utilizes the metabolic characteristics of anaerobic microorganisms, uses the reduced organic matter in sewage as a hydrogen acceptor without the need to provide exogenous energy, and produces methane gas with energy value. Waste organic matter can be converted into biogas and biogas residue, which can be used to replace fossil energy such as coal for power generation, thereby effectively reducing environmental pollution caused by the combustion of fossil energy. Biogas residue can be used as organic fertilizer to reduce the pollution of soil by chemical fertilizers. At present, biogas preparation often consumes a large amount of external fossil energy to continuously heat and stir the biogas slurry, which reduces the net output proportion of biogas to a certain extent.

[0004] The existing anaerobic fermentation tank stirring device, when stirring, because the sewage and organic matter in the anaerobic tank will form layers, the conventional stirring device cannot fully stir the organic matter and sewage inside the anaerobic tank. It is impossible to turn over the internal layered materials so that they can be quickly stirred by the stirring component, resulting in low mixing efficiency when the sewage and organic matter are mixed and stirred, and it is impossible to quickly and efficiently promote decomposition.

DETAILED DESCRIPTION

[0040] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention.

[0041] like Figure 1 - Fig.11 As shown, the present invention provides an anaerobic fermentation tank stirring device for sewage treatment, and the anaerobic tank 10 is used to contain sewage, which can be buried underground to store sewage. A fermentation bin 11 is provided inside the anaerobic tank for containing sewage and organic matter to be treated. Among them, the fermentation bin 11 is the main area for anaerobic microorganisms to degrade organic matter. The organic matter in the sewage can be decomposed into inorganic matter, such as carbon dioxide and methane, by anaerobic microorganisms, so as to purify the water quality. The stirring port 12 provided above the fermentation bin 11 can provide convenience for subsequent stirring operations. It is ensured that the stirring device can be effectively placed in the fermentation bin 11 for stirring. The drive assembly 20 is the power source of the entire stirring device. The drive assembly 20 is firmly mounted above the stirring port 12 by the fixing plate 21 to ensure stability during operation. Among them, the drive assembly 20 can provide sufficient power to support the operation of the transmission assembly 30, the stirring assembly 40 and the flipping assembly 50.

[0042] The transmission assembly 30 receives the power of the driving assembly 20 and transmits it to the stirring assembly 40 and the flipping assembly 50, so that the stirring rod 41 can operate at the set speed and direction, thereby completing the stirring. At the same time, the flipping assembly 50 and the stirring assembly 40 can be driven to work simultaneously according to the use requirements, which can further promote the reaction of sewage and organic matter in the anaerobic tank 10. Among them, the transmission assembly 30 includes a transmission plate 31 and a transmission gear 32. Among them, the transmission plate 31 is rotatably arranged on the mounting plate 212, and the transmission plate 31 can convert the power generated by the adjustment push rod 23 into the power of moving up and down by connecting the transmission slider 34 and the transmission converter 35, thereby driving the flipping assembly 50 to move. Among them, the transmission gear 32 is fixed at the output end of the driving assembly 20, and is responsible for effectively transmitting the power generated by the driving assembly 20 to the stirring assembly 40. The setting of the transmission assembly 30 not only ensures the high efficiency of power transmission, but also improves the reliability and durability of the entire device. The transmission assembly 30 further includes a driving mechanism for driving the transmission plate 31 to perform a swinging motion. The driving mechanism drives the transmission plate 31 to perform a swinging motion along the rotating hole 213 provided on the mounting plate 212 .

[0043] The stirring assembly 40 is used to stir the sewage and organic matter in the fermentation bin 11 to ensure that the decomposition of organic matter can be promoted. Among them, the stirring assembly 40 includes a stirring rod 41, which is the core part of the stirring assembly 40, used to transmit stirring power, and can provide support for the installation of the stirring blade 43. By fixing the transmission gear 32 on the top of the stirring rod 41 and connecting it to the output end of the drive assembly 20. The rotational power generated by the drive assembly 20 can be transmitted to the stirring rod 41, so that the stirring rod 41 can rotate according to the set speed and direction. The connector 42 is a connecting component between the stirring rod 41 and the stirring blade 43, which adopts a detachable design for easy installation and maintenance. Among them, the setting of the connector 42 can ensure the stability and reliability of the stirring blade 43 during the rotation process, while reducing energy loss. The stirring blade 43 is the part that directly acts on the material in the fermentation tank, which can generate strong shear force and turbulence when rotating, and promote the mixing and homogenization of the material.

[0044] The turning assembly 50 is used to turn over the sewage and organic matter in the fermentation bin 11, so that the sewage and organic matter layered at the top and bottom can form convection, thereby promoting mixing and accelerating decomposition. The turning assembly 50 includes a lifting rod 51, which is a key component for the stable operation of the turning assembly 50. The lifting rod 51 is fixedly connected to the transmission converter 35, and because the transmission converter 35 is slidably connected to the transmission plate 31, the lateral movement of the adjustment push rod 23 can be converted into the lifting movement of the lifting rod 51, and accurate position adjustment and height control can be achieved. Specifically, a threaded section 511 is provided on the outside of the lifting rod 51, and matches the threaded hole 214 on the fixed plate 21. Through the threaded connection method, the lifting rod 51 can be accurately moved vertically under the action of the adjustment push rod 23, thereby achieving the position adjustment of the turning assembly 50. It can then drive the spiral blade 52 fixed on its outside to move up and down. Among them, the spiral blade 52 is the part of the turning component 50 that directly acts on the material in the fermentation bin 11. It has a large surface area and a strong stirring ability. It can generate strong shear force and turbulence when rotating, and promote the up and down turning and mixing of the material. The turning component 50 acts on the material inside the fermentation bin 11, and the material in the fermentation bin 11 is turned and mixed to promote the uniform reaction and full decomposition of the material. Specifically, when the turning component 50 on one side is driven by the transmission component 30 to move upward, the turning component 50 on the other side moves downward accordingly, and can form a turning convection in the fermentation bin 11. The generation of turning convection allows the material in the fermentation bin 11 to be more evenly and fully stirred, thereby improving the reaction rate and product quality.

[0045] It should be noted that a protective cover is hingedly provided at the stirring port 12. When stirring is not required, the stirring device can be disassembled, and the sealing of the anaerobic tank 10 can be ensured by the protective cover. Among them, the anaerobic tank 10 is provided with a water inlet, which can ensure that sewage enters the anaerobic tank 10 and is then treated in an anaerobic environment. It is also equipped with a water outlet, which can discharge the treated water out of the anaerobic tank 10 through the water outlet, enter the subsequent treatment process or be directly discharged into the water body. Among them, a sludge discharge port is also provided at the bottom of the anaerobic tank 10, which is used to regularly remove the sludge and other sediments accumulated at the bottom of the anaerobic tank 10. Specifically, when the stirring device is in use, it is also equipped with a temperature control system for use in conjunction with it to ensure that anaerobic microorganisms can grow under optimal conditions, thereby improving the efficiency and effect of sewage treatment.

[0046] like Figure 3 - Figure 7As shown, the fixed plate 21 is the basic supporting component of the entire driving assembly 20, which can ensure the safe use of the driving assembly 20, and is composed of a base plate 211 and a mounting plate 212. The base plate 211 is fixedly arranged above the stirring port 12, and a rotating hole 213 and a threaded hole 214 are opened on the base plate 211. Among them, a rotating bearing 215 is fixedly arranged in the rotating hole 213, and a stirring rod 41 is fixedly connected through the rotating bearing 215, which can ensure the stability of the stirring rod 41 during use, and ensure that the stirring rod 41 will not shake or fall off during stirring. The threaded hole 214 is used to rotatably connect the lifting rod 51. By being threadedly connected to the lifting rod 51, the lifting rod 51 can drive the spiral blade 52 to rotate when it moves in the vertical direction.

[0047] Preferably, the drive assembly 20 also includes a drive motor 22, which is the main core drive of the drive assembly 20 and can provide driving force for the device. By fixing a drive shaft 221 at the output end of the drive motor 22, the power generated by the drive motor 22 can be effectively transmitted. The drive shaft 221 is rotatably connected to the connection hole 216 opened on the mounting plate 212 to ensure that the power can be smoothly transmitted to the transmission gear 32. Specifically, the connecting bearing 217 is fixed in the connection hole 216, and its interior is fixedly connected to the outside of the drive shaft 221, which can play a role in supporting and reducing friction, ensuring the power transmission of the drive shaft 221. Among them, the adjustment push rod 23 is fixed on the mounting plate 212, which can effectively drive the transmission assembly 30 above the mounting plate 212 to move, and then drive the flip assembly 50 to move up and down through the transmission assembly 30, so that the flip assembly 50 flips the sewage and organic matter in the fermentation bin 11 to meet different work requirements.

[0048] In this embodiment, when the driving motor 22 is started, the driving shaft 221 at its output end can be driven to start rotating. Since the driving shaft 221 is fixedly connected to the connecting bearing 217 in the mounting plate 212, it can ensure that the power of the driving motor 22 is transmitted to the transmission gear 32 fixedly arranged at the other end of the driving shaft 221, and then the power is transmitted to the stirring rod 41 through the transmission gear 32. Among them, the stirring rod 41 starts to rotate under the support of the rotating bearing 215 to stir the materials in the fermentation bin 11. At the same time, by starting the adjustment push rod 23, the power can be applied to the transmission plate 31, and then the power is transmitted to the top of the lifting rod 51 through the transmission plate 31. Since the lifting rod 51 is threadedly connected to the threaded hole 214, it can be rotated under the guidance of the threaded hole 214, thereby driving the spiral blade 52 to rotate and completing the turning of the material.

[0049] like Figure 2 - Fig. 9As shown, the transmission gear 32 is the core part of the transmission assembly 30, and is composed of a driving gear 321 and a driven gear 322. By fixing the driving gear 321 on the other end of the driving shaft 221, the power generated by the driving motor 22 can be received. Among them, by meshing the driven gear 322 with the driving gear 321, and fixing the driven gear 322 on the top of the stirring rod 41, the power generated by the driving motor 22 can be transmitted to the stirring rod 41, ensuring the effective transmission and conversion of power, while improving the transmission efficiency.

[0050] Preferably, in order to achieve precise adjustment of the driving mechanism, the driving mechanism further includes a transmission rail 33 and a transmission slider 34. By fixing the transmission rail 33 above the mounting plate 212, a stable sliding path can be provided for the transmission slider 34, ensuring that the transmission slider 34 can effectively drive the transmission plate 31 to rotate along the driving shaft 221. Among them. By fixing the transmission slider 34 to the output end of the adjustment push rod 23, the transmission slider 34 can slide in the transmission rail 33 through the push of the adjustment push rod 23, so that the transmission assembly 30 can adjust the position of the flip assembly 50 as needed to meet different work requirements.

[0051] Preferably, the transmission plate 31 is a key bridge connecting the transmission slider 34 and the lifting rod 51, and the transmission plate 31 is sleeved on the outside of the driving shaft 221. A transmission groove 311 slidably connected to the transmission shaft 341 and a sliding groove 312 for ensuring the sliding of the transmission converter 35 are provided. By slidingly connecting the transmission shaft 341 with the transmission groove 311, the transmission plate 31 can be effectively driven to rotate along the driving shaft 221 through the transmission shaft 341. Among them, by setting the sliding groove 312, it can be ensured that the sliding pin 351 in the transmission converter 35 cooperates, so that the transmission converter 35 slides on the transmission plate 31, and then converts the power, thereby transmitting it to the lifting rod 51. Among them, the transmission converter 35 can slide in the sliding groove 312, and is fixedly connected to the top of the lifting rod 51 through the fixing groove 352 and the conversion bearing 353 at the bottom, so that the transmission assembly 30 can flexibly adjust the position of the lifting rod 51, thereby realizing accurate control of the material turning.

[0052] In this embodiment, when the driving motor 22 is started, the driving shaft 221 at its output end drives the driving gear 321 to rotate. The driving gear 321 meshes with the driven gear 322 to transmit power to the stirring rod 41, so that the stirring rod 41 starts to rotate and stirs the material. At the same time, when the adjusting push rod 23 is started, the transmission slider 34 in the driving mechanism is driven to move on the transmission slide rail 33, and then the transmission shaft 341 on the transmission slider 34 is driven to slide in the transmission groove 311 opened on the transmission plate 31, and then the transmission plate 31 is driven to move. Since the transmission plate 31 is fixedly connected to the connecting bearing 217, the transmission plate 31 is driven to rotate along the driving shaft 221, and under the action of the transmission shaft 341, the transmission converters 35 on both sides can be driven to move in the sliding groove 312 respectively, so that the transmission converter 35 on one side rises and the other side falls. Since the bottom of the transmission converter 35 is fixedly connected to the lifting rod 51 through the conversion bearing 353. When the transmission converter 35 rises or falls, it drives the lifting rod 51 to rise or fall, causing the threaded section 511 and the threaded hole 214 on the lifting rod 51 to rotate, thereby prompting the spiral blade 52 fixed on the outside of the lifting rod 51 to rotate, completing the turning of the fermentation bin 11.

[0053] like Figure 3 - Fig.11 As shown, the connector 42 is a key component for connecting and adjusting the stirring blade 43. By fixing an adjusting motor 421 inside it, power can be provided for the angle adjustment of the stirring blade 43. Among them, the adjusting gear 422 is a bridge connecting the adjusting motor 421 and the stirring blade 43. By fixing the adjusting gear 422 at the output end of the adjusting motor 421, the power generated by the adjusting motor 421 can be transmitted to the stirring blade 43 through the meshing relationship, so that the stirring blade 43 completes the angle adjustment. It should be noted that by providing an angle scale mark on the outside of the connector 42, it is convenient for the operator to intuitively understand the angle position of the stirring blade 43 and adjust it as needed. Ensure the accuracy and controllability of the stirring process. When it is necessary to stir the fermented material in the anaerobic tank 10 at multiple angles, start the adjusting motor 421 and drive the adjusting gear 422 to rotate. The adjusting gear 422 is connected by meshing with the stirring blade 43 to drive the stirring blade 43 to rotate and adjust. As the angle of the stirring blade 43 changes, its stirring effect on the material will also change accordingly. By continuously adjusting the angle of the stirring blade 43, all-round and multi-angle stirring of the material can be achieved, thereby promoting a full reaction of the material.

[0054] The working principle of the present invention is as follows: when a stirring device is required, the fixed plate 21 is fixedly arranged at the stirring port 12 above the anaerobic tank 10. By starting the driving motor 22, the driving shaft 221 drives the driving gear 321 to mesh with the driven gear 322, thereby driving the stirring rod 41 fixed at the bottom of the driven gear 322, and the connector 42 arranged on the outside of the stirring rod 41 can effectively drive the stirring blade 43 to mix and stir the sewage and organic matter in the fermentation bin 11. When the sewage and organic matter in the fermentation bin 11 are stratified, the stirring assembly 40 alone cannot quickly mix and decompose the organic matter and sewage in the fermentation bin 11. At this time, by starting the adjusting push rod 23, the transmission slider 34 is driven to move on the transmission slide rail 33, thereby driving the transmission shaft 341 to slide in the transmission groove 311, and then the driving force acts on the transmission plate 31 through the transmission shaft 341. Since the transmission plate 31 is fixed on the mounting plate 212 through the connecting bearing 217, it can rotate along the center of the connecting hole 216. Then, the transmission converter 35 at both ends is driven to be raised and lowered through the sliding groove 312. Since the bottom of the transmission converter 35 is fixedly connected to the lifting rod 51 through the conversion bearing 353, the lifting rod 51 can be driven to move. When the lifting rod 51 rises or falls, the threaded section 511 arranged on the outside thereof will act on the threaded hole 214 on the bottom plate 211, thereby driving the lifting rod 51 to rotate, and the spiral blade 52 arranged on the outside thereof can be driven to turn over the stratified sewage inside the fermentation bin 11. This helps to evenly mix and react the materials, and can also effectively prevent the agglomeration and sedimentation of the materials during the fermentation process.

[0055] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
